Hi, I am an RF beginner. At present, I try to experiment with communication system using MATLAB with blade RF. I have tried the transmission of AM signal modulation and observed the result.
As following:
Have seen other people use other systems to view the constellation verification QPSK, but I have encountered bottlenecks in the use of simulink construction, I do not know how to generate QPSK signal for blade RF sent.
I begged to provide some suggestions and methods, or related construction principles, this question confused me for a long time.
